like a moth to frame quest bug

[Everice]

the quest bug at the first moth with Lenora. as she was missing where she is(the quest icon was there) but i somehow can use lumos to reveal the image location where the moth is. i went to find it and returned it to the frame without talking to Lenora. then i came back and saw Lenora looking at the wall. i talked to her and quest started that's where the problem is

In my experience, that issue will resolve itself. Even you already found it, at some point you get the same dialog where you tell her you figured it out. I am not sure what triggers it, but it may be once you have done the second in Hogwarts.
